Abstract

New routing algorithms are being developed to reduce power consumption, effective utilization of resources and best route to a specific destination in wireless mobile ad hoc network. To simulate the algorithm, interaction between the different layers of the OSI, the link available and furthermore, employing a suitable propagation model in a wireless environment, the use of network simulators do eliminate irrelevant issues pertaining to the actual work which is testing the algorithm. This paper presents the development of the simulation model to test a new routing protocol called quadrant-based directional routing protocol (QDIR). Q-DIR uses exact location of nodes based on Cartesian-coordinate system to restrict the broadcast region to only a quadrant where the destination node and source node are located. Unlike other positionbased routing protocols, Q-DIR transmits route request to all nodes that are in the same quadrant as the source and destination instead of broadcasting in all direction. This in return will reduce not only routing overhead in route discovery phase, but also wireless bandwidth used and collision of packets in the network. Neighboring nodes that are in the same quadrant will participate in this route determination phase.
